ISOTHERMAL AND NON-ISOTHERMAL MULTICOMPONENT ADSORPTION KINETICS
Chemical Engineering Communications, 1990The model equations in the relaxation form for the multicomponent kinetics of isothermal and non-isothermal adsorption, taking into account all major distinctive features of the interphase heat and mass exchange inside porous grains and at their surface (see points 1 to 4 below) for P (“pore”) and S (“solid”) models of mass transfer within porous ...

Freundlich's adsorption isotherm
Surface Science, 1973Abstract We present a brief derivation of Freundlich's adsorption isotherm using straightforeward methods of statistical mechanics. The assumption that the adsorbed atoms move in Morse potential wells of different depths leads to the observed compensation effect in the energy dependence of the occupation probability of surface sites, essential for ...

Nature, 1951
THREE years ago, Huttig1 derived a multilayer adsorption isotherm which in most cases agrees with experiment up to higher relative pressures x = p/p0 (where p0 is vapour pressure of the liquid adsorbate) than the Brunauer–Emmett–Teller2 isotherm. Huttig's formula, however, is not in accord with the kinetic assumptions implied in the derivation and does

Monomolecular adsorption isotherms
Journal of Colloid and Interface Science, 1980There is a mathematical similarity between Jovanovich and Langmuir isotherms. They can be derived from integration of the differential equation. (dθ/dp) = c(1 − θ)k, when k = 1 and k = 2, respectively. Other isotherms which satisfy certain theoretical conditions of monomolecular adsorption may also be derived from the differential equation when k is ⩾1.

This study investigates the adsorption behavior of a specific solute (e.g., a heavy metal ion or an organic dye) from an aqueous solution onto a novel adsorbent material (e.g., activated carbon, biochar, or a composite). The main objective is to determine the equilibrium relationship between the solute concentration in the bulk solution and the amount ...
